Conversation
A record says whether it succeeded, never why it ended. The distinction that
was missing is timeout versus failure: SubprocessError flattens a timeout to
returncode=-1, so a run the harness killed at its wall-clock budget and a run
that crashed produce the same record.
SubprocessError now carries timed_out, and each CLI harness maps its exit into
AgentResult.terminal_reason ("" | completed | timeout | error), which reaches
the row as terminalReason. A killed run still reads status: "success", so
without this an efficiency ceiling is indistinguishable from a bad answer.
A CLI agent's own internal turn cap is invisible from outside the process, so
a capped run lands in "completed".
The trajectory already records every tool call, but it is a per-run blob the dashboard cannot aggregate over. Two models with the same score and the same wall clock can differ severalfold in how much work they did to get there, and nothing on the row said so. Adds toolCalls and toolErrors, computed in build_rows from the record's trajectory. No new capture: the data was already on disk. tool_errors counts "error" and "interrupted" — an interrupted call produced no result either, so counting only "error" would report a run killed mid-tool as clean. "called" is excluded: it means the parser never saw the call resolve, which is a gap in our capture rather than a tool the model broke.
toolErrors counted 'interrupted', which only the antigravity parser emits, and for the identical condition four other parsers label 'called'. The column was not comparable across the harness dimension the dashboard groups by. toolCalls/toolErrors now read None on an empty or absent trajectory. A trajectory export can fail on its own (six early returns in the openclaw harness) and a 0 there reads as 'made no tool calls'. Mirrors model_turns, which already makes this distinction.
`normalize_tokens` matched only snake_case cache aliases, but the CLI
harnesses pass their tool's own usage keys through verbatim, so the
tool's spelling is part of the contract. OpenClaw spells them
`cacheRead` / `cacheWrite` / `totalTokens`, none of which matched, so
`cachedTokens` came out `None` on every OpenClaw row and the cache
tokens vanished from the bucket breakdown.
Live `oc` run before this change:
raw {"input": 26362, "output": 23, "cacheRead": 24388, "total": 50773}
buckets input=26362 output=23 cached=None -> sum 26385 vs total 50773
48% of the run's billed tokens unaccounted for, and the shortfall grows
with conversation length because cache reads are what a long agentic
session accumulates. After: sum == total, on a fresh live run where the
cache read had grown to 32516 of 50769 tokens.
`cacheWrite` and `totalTokens` come from the same source and are added
alongside. `@openclaw/ai`'s `parseChunkUsage` builds every provider
adapter's usage as `{input, output, cacheRead, cacheWrite, totalTokens}`
with `input` already net of both cache buckets and its own total defined
as their sum, so the four map onto our buckets without any subtraction.
Canonical snake_case keys keep lookup priority, so a record carrying both
spellings is unaffected. The nested `cost` map OpenClaw emits beside the
counts repeats the same bucket names with dollar values; lookup stays
top-level only, and a test pins that.
… run The CLI harnesses timed the whole of `_execute`, so workspace setup and post-run transcript recovery were billed to the agent. Measured live on openclaw: 9.80s reported for a 6.84s turn — 1.67s of trajectory export plus 1.30s of skill/config materialization, 30% of the number. That number is about to be ranked (lower-is-better), and the overhead is not evenly distributed: openclaw and antigravity both do post-run recovery, gemini_cli parses from stdout and does none. Ranking on it would order harnesses by how much work we do after they finish. All three now stamp `latency` around the subprocess call only, which `AgentHarness.run` leaves alone because it only fills in a zero. The error paths carry the elapsed span too, so a timeout no longer reports 0.
`model.completed.usage` is the rollup the parser already sums, and it drops exactly one bucket: `cacheWrite`. That field appears only on the per-call `assistant.message.usage` events, so every openclaw row shipped `cacheWriteTokens = None`. Verified against a live export that the per-call usages sum to the `model.completed` total for every other bucket, to the token — so taking `cacheWrite` from the per-call events and leaving the rest to the rollup keeps one accounting basis rather than mixing two. Cache writes are priced above plain input on Anthropic (1.25x at 5min, 2x at 1hr) and are free on Google, so the missing bucket makes an Anthropic run through openclaw look cheaper than it was billed. Also documents that openclaw reports no reasoning bucket at any thinking level (checked live at `off` and `high`), so `reasoning` stays None rather than a fabricated 0.
"Timed out" and "finished with room to spare" are the same row today. `timeout_sec` is a run setting nothing downstream can recover after the fact, so it goes on the manifest and rides onto each row. The row copy is not redundancy for its own sake: ingest uploads rows.json alone and never reads manifest.json, so a manifest-only field never reaches the dashboard. setupId/model/harness/runId/t are duplicated onto the row for exactly this reason already. `max_turns` is deliberately left off. Only the API agent reads it, so stamping it would advertise a CLI arm a budget that never bound it.
`toolCalls` was standing in for how many times the model was called, and those are not the same number. A live openclaw run just now returned `model_turns=2` against `tool_calls=1`: one message issued the shell call and a second, text-only turn wrote the answer. The reverse happens too — an earlier run had a single `assistant.message` carrying two `toolCall` entries. The distinction matters because an agentic loop re-sends the whole conversation every turn, so input tokens grow with turns, not with tool calls. Cost-per-turn read off `toolCalls` is wrong by that factor, and a model that batches its calls looks identical to one that serializes them. Sources, per harness: - openclaw: count `assistant.message` events in the trajectory export. `parse_trajectory_export` now returns a `TrajectoryExport` NamedTuple so the extra field does not turn the return into an anonymous 5-tuple. - antigravity: the conversation DB already decoded one usage record per round-trip; `db_token_state` now returns that count alongside the tokens, as a `DbTokenState` NamedTuple. - gemini_cli: left `None`. Its stream is delta messages with no clean turn boundary, and guessing one would put a fabricated number next to two measured ones. Unreported stays `None`, never `0` — a run that produced output cannot have taken zero round-trips, so `0` would be a parse miss dragging down a dashboard average. The shared `_coerce_int` rejects bools, since `True` is an `int` in Python and would otherwise normalize to one turn. Validated live against openclaw (gemini-3-flash-preview): `model_turns=2`, `tool_calls=1`, clean terminal reason. Antigravity could not complete a live turn on this host (project permission denied), so its path is covered by unit tests over proto blobs captured from a real DB.
much of it the model spent thinking versus waiting on `kubectl` against a
cold cluster. A run slowed by its environment is currently indistinguish-
able from a slow model, and the environment is the part that is not the
model's fault.
The plan assumed this was API-only telemetry because CLI transcripts carry
no timestamps. They do — every openclaw event has a top-level `ts` and
every gemini_cli stream event a `timestamp`, both ISO-8601 with
milliseconds, and both pair calls to results by id. So both CLI harnesses
can report it:
openclaw tool_wait_sec=0.203 latency=7.40
gemini_cli tool_wait_sec=0.035 latency=6.44
Overlapping calls are merged rather than summed. A single openclaw message
issued two calls stamped at the same millisecond; adding their durations
would report more time inside tools than the run took end to end. The
merge helper lives in `agents/shared/timing.py` because both parsers need
the same rule.
`0.0` stays on the row — tools that returned inside the transcript's
resolution really did measure zero — while a harness reporting no
timestamps stays `None` so it is left out of an average instead of pulling
it toward zero. That is the opposite of the `model_turns` rule, and
deliberately so.
Not done for antigravity: I could not get a live `agy` turn on this host
(project permission denied), so whether its transcript stamps events is
unverified and it reports `None`.
`ToolCall` deliberately gains no per-call `duration_sec`. Nothing consumes
it, the row cannot carry a list, and adding it would change the trajectory
shape every parser and the API agent emit.
`ResultRow.model` is the model the run *requested*. That is not always the one that served it. openclaw fails over to another provider mid-run on an auth or quota error and keeps going, and both CLIs resolve aliases — a run configured for `gemini-3-flash` came back served by `gemini-3-flash-preview`. A leaderboard row therefore attributes a score to a model that may not have produced it, and there is no way to tell from the row. Both CLI transcripts already say who answered: - openclaw: `assistant.message.model`, per call, so a mid-run failover appears as a second distinct id. - gemini_cli: `init.model` for the resolved id, plus every key of `result.stats.models`, which is keyed per serving model. Distinct ids in first-seen order, comma-joined onto `servedModel`. More than one entry is the failover signal, so collapsing to the first would hide the case the field exists for. Empty string when the harness reports nothing, which is how antigravity reads — I could not get a live `agy` turn on this host to see whether its transcript names the model. Live: openclaw `['gemini-3-flash-preview']`, gemini_cli `['gemini-3.5-flash']`.
A five-reviewer panel plus an adjudication pass over the consolidated branch. Six findings survived verification; each is fixed here. Cache writes were missing from the total. `model.completed` omits `cacheWrite` from its buckets *and* from the `total` it reports, so a total copied through verbatim understated every openclaw run by exactly the bucket the change exists to surface -- 523 against a bucket sum of 542 on the live capture the tests are built from. `TOKEN_BUCKETS` documents `total` as the sum of all buckets, so the recovered bucket is now folded back into the rollup total. The normalize.py comment claiming openclaw's total already includes cache writes described `parseChunkUsage`, which is the *per-call* total, not the session rollup; it said the opposite of the parser's own docstring and fixture, and is corrected. API-arm timeouts were labelled `error`. `AgentResult.errored` defaults `terminal_reason` to `"error"`, and the API agent's wall-clock timeout path never passed one, so a run cut off at its budget landed in the same bucket as a provider crash -- the exact conflation the field was added to remove, and worse than the `""` reserved for untaught harnesses because it asserts a wrong value rather than none. Its success path now reports `completed` too, so the arm is comparable rather than permanently blank. Timed-out rows carried no telemetry. Openclaw returned before extracting its trajectory, and gemini discarded the partial stdout that `core.subprocess` captures off `TimeoutExpired` -- so a run killed after forty tool calls and one killed before its first were the same empty row, on exactly the rows where how far it got is the question. Both now recover what the run managed, as antigravity already did. Openclaw also reads `exc.timed_out` rather than assuming every `SubprocessError` under `check=False` is a timeout; its test raised a non-timeout error and asserted the timeout path, so the fixture was pinning the assumption rather than the behaviour. The `cacheWrite` skip in `_accumulate_usage` fired at every recursion depth, deleting the cache-write line from a nested `cost` breakdown. The token bucket is skipped to keep one source; cost dollars have no second source, so the skip is now top-level only. `count_tool_calls` returned a fabricated `(0, 0)` when a non-empty trajectory held nothing but non-mappings -- a confident zero on the corrupted records the mapping filter exists to survive. Empty-after- filtering is now the same "not captured" `None` as empty-on-arrival. Also corrects three docstrings that drifted from the code they sit beside: `latency` is stamped by `_execute` and only backfilled by `run()`; the gemini event table claimed a terminal status is read from the `result` event, which it is not; and `StreamParse.errors` also collects the stream's own `error` events, such as rate limits.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Count only canonical tool-call entries so an interleaved text turn cannot inflate toolCalls, stamp the antigravity agent span before credential cleanup, and scope the docs' total-token guarantee to canonical telemetry. Also makes the openclaw elapsed-time test exercise the timeout path it claims to cover.
An empty trajectory alone cannot say whether the agent called no tools or the transcript export failed. The record already carries the tiebreaker: every path that loses a transcript reports why in errors, so an empty trajectory beside an empty errors list is a genuine zero.

Conflict in devops_bench/agents/result.py: AgentResult.errored gained tokens=empty_tokens() on main and terminal_reason on this branch. Kept both.
Claude Code reported none of the four per-run telemetry fields the rest of the harnesses now populate. Derive them from the stream-json events: - terminal_reason: bucket the CLI's own reason (19 values) into the bench's four, keeping the specific one on errors. The harness's own timeout and a non-zero exit outrank whatever the stream claimed. - model_turns: count distinct assistant message ids, not the terminal event's num_turns -- the CLI emits one envelope per content block, so a single API message answering with two tool_use blocks inflates num_turns. - tool_wait_sec: pair each tool_use with the tool_result answering it using the envelope timestamps, concurrent calls counted once. duration_ms minus duration_api_ms is unusable: it goes negative on real runs. - served_models: read the assistant envelopes, not result.modelUsage, whose keys include the CLI's internal helper model. parse_stream_json now returns a StreamParse NamedTuple, matching the shape the gemini-cli parser already uses.
- Score a turn-capped run as ``completed``, matching the documented ``TERMINAL_REASONS`` contract and the sibling harnesses; the cap still reaches ``errors``. Invert the agent-level precedence so the stream's terminal event outranks the exit code, since the CLI exits 1 on a cap. - First terminal event wins for ``terminal_reason`` and ``errors``, so a degenerate second event cannot append a failure the reason contradicts. - Prefer the CLI's own ``terminal_reason`` over the failure flags when naming the error, so ``prompt_too_long`` is not an anonymous failure. - Skip the CLI's synthetic ``is_api_error_message`` envelope for usage, ``model_turns`` and ``served_models``: no model was called. - Treat an empty message id as unidentified rather than merging every such envelope into one turn and dropping their usage. - Read ``SubprocessError.timed_out`` instead of assuming a timeout. - Share ``note_model`` across the three CLI parsers.
